CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 263,800, dated September 5, 1882.

' Application filed June 23, 1882. (No model.)

' closes the openingor front of the draw-head and receives the impact of the approaching link,whereby itis raised and falls again through the link to secure it.

My invention consists in the details of construction, as hereinafter set forth and claimed.

Referring to the accompanying drawing, Figure 1 is a vertical section.

Let A represent the end of an ordinary boxcar, under which, in the usual manner, is secured adraw-head, B. This has theusualchannher, a, and is provided with a flaring face, I). In its bottom is made an aperture, 0, the front wall of which is vertical, and the rear wall is beveled from the rear downwardly, as shown. The top of the draw-head is provided with an aperture, cl, the rear wall of which is curved. The front walliis inclined from the inside or lower edge backwardly, forming a point, 0, and thence forwardly in a concave curve, coding in a convex curve, as shown.

C is the latch. This consists of two arms, 0 and 6, extending about at right angles and meeting at their bases in a hub, 6 the outer face of which is rounded and fits in the concave curve of the front wall of aperture, 01.

This latchis hinged in the front of the said aperture by a pivot, D, through the walls of the draw-head and through the hub e. The

arm 0 upon its forward side is notched out at 0. When at rest in the aperture d, the latch lies with its arm 6 extending downwardly across the chamber to. Its lower end is curved backwardlyand upwardlyand fitsdowninto aperture 0, its front abutting against the straight pushed back and up upon the pivot D, the

'ing and throwing the arm 0 up out of aperture d. When the link has passed the arm e the latch G returns to position, the arm 0 falling through the link and the arm 0 returning within aperture d. The strain is resisted by the arm 6, which has two points of impingement-namely, one below against the-front wall of aperture 0 and one above against the front wall of aperture d. The point 0, fitting in notch o, lends support to the latch and resists the strain upon the link. It also prevents the latch, should the pivot-pin D work out, from working up through aperture d. It may become necessary sometimes to lift the latch Q and throw it back in a position in which it will remain without falling. For this purpose enough space is left between the pivot D and the upper portion of the rear of the draw-face to change the center otgravity to a point for-' ward of the pivot-pin.

end of the rod is provided with a knob, 9L,

and has upon its inner side a series of ratchetteeth, 0'. y

Upon top of the car and extending over the end is a pawl, s, with which the teeth 4 engage when the rod is raised to secureit at any height.

To the rod E, near its lower end, is secured an arm, 1*, to the end of which a chain, G, is attached, the other end of which is secured to the rear end of arm 6 of latch C. By raising the rod E the latch 0 may be drawn up to free its arm 6 from the link. When therod is released from the pawl s the latch drops back into position.

The aperture 0 in the bottom of the drawhead not only furnishes a point of resistance for the arm e, but is for the purpose of allowing stones, &c., to drop through, to prevent any obstruction to the said arm in finding its place. This is an advantage, as it keeps the arm from becoming worn.

. Having thus described my invention,what I claim as new, and desire to secure by Letters '8, arm F upon said rod, and chain G, connect- Patent, is- I ing said arm with the arm 0 of latch 0, sub- In a ear-coupling, the draw-head B, having stantially as and for the purpose herein dea chamber, a, a bottom aperture, 0, and a top scribed.
